•  Flux Cored Brazing Wire AL02-Zn98Al2, for Copper to Aluminum Brazing (Zn-Al alloy) Packaging

  Filler metal shall be suitably packaged to ensure against damage during shipment and storage under normal conditions.        

  The following product information (as a minimum of low temperature aluminum welding wire)         

  shall be legibly marked so as to be visible from the outside of each unit package:         

  (1) AWS specification and classification designation (year of issue may be excluded best wire for welding aluminum)         

  (2) Supplier's name and trade designation         

  (3) Size and net weight         

  (4) Lot, control, or heat number        

1.  Welding fumes can be hazardous to your health. Work in a well-ventilated area or use a local exhaust (fume extraction) system to keep fumes away from your breathing zone .

2. Wear correct eye, ear, and body protection. Use welding goggles or a helmet with a shade 4-5 lens for gas welding , along with heat-resistant gloves and protective clothing . To avoid skin contact, follow standard precautions: wash thoroughly after handling, and do not allow contaminated work clothing to leave the worksite .

3.  Avoid overheating. Excessive heat will cause zinc to evaporate from the alloy, producing excessive white fumes and leading to weld defects like porosity and reduced joint strength . Use a neutral or slightly oxidizing flame and control the heat input carefully to minimize zinc loss. Also, note that this filler metal is not suitable for furnace brazing in a controlled atmosphere due to zinc volatilization issues .

Flux Cored Brazing Wire AL02-Zn98Al2 VS ERCuSi-A?

AL02-Zn98Al2 flux cored brazing wire and ERCuSi-A serve completely different joining technologies. AL02-Zn98Al2 is a self-fluxing zinc-aluminum brazing filler metal for low-temperature dissimilar copper-to-aluminum brazing at 430~460°C, commonly used for heat exchangers. ERCuSi-A is AWS A5.7 silicon bronze solid welding wire for fusion welding of copper, brass and copper-to-steel. It cannot be used for copper-aluminum joining due to high melting temperature and brittle intermetallic formation. AL02 has no AWS classification, while ERCuSi-A is a standard AWS A5.7 classification.

Flux Cored Brazing Wire AL02-Zn98Al2 VS ERCuSn-A?

AL02-Zn98Al2 flux cored brazing wire and AWS A5.7 ERCuSn-A phosphor bronze welding wire belong to different joining categories. AL02-Zn98Al2 is a self-fluxing zinc-aluminum brazing filler metal for low-temperature dissimilar copper-to-aluminum brazing at 430~460°C, widely used for refrigeration heat exchangers. ERCuSn-A is solid phosphor bronze fusion welding wire for MIG/TIG welding of copper, brass, bronze and copper-to-steel components. It cannot be used for copper-aluminum joining because high welding heat creates brittle intermetallic layers. AL02 has no AWS classification, while ERCuSn-A is classified under AWS A5.7.
